The bottom of the tension adjustment component 14 is threaded to the outer wall of the first lead screw 20.

[0040] The spring 11 allows the tightening plate 9 to retract downwards via the connecting column 10, thus fixing one end of the fiber filament during curing, facilitating subsequent tension and length adjustment.

By activating the second servo motor 32, the second lead screw 31 can be rotated, causing the front drive block 29 to move the laser length measuring instrument 28 to a suitable position. The laser signal receiver 15 then limits the length of the fiber filaments.

At the same time, the scraper 38 can prevent the resin from sticking to the outer wall of the recycling component 33 and also has a certain cleaning effect.

[0045] like Figure 1-6 As shown, a method for using a microwave curing tunnel oven for ultra-large diameter carbon fiber composite materials includes the following steps:

[0046] S1: Lift handle 13 upwards to move the tightening plate 9 away from the inner cavity of the first tightening groove 8, and wind the left side of the fiber filament around the outer wall of the winding post 7. After releasing handle 13, spring 11 drives the tightening plate 9 to press down through connecting post 10, thereby fixing the winding post 7. Place the right side of the fiber filament in the inner cavity of the second tightening groove 16, start the electric slide rail 18, and drive the anti-slip pressure plate 17 to press down until the fiber filament is clamped.

[0047] S2: The molten resin material is injected into the inner cavity of the feeding roller 22 through the feed pipe 24.

After moving to the bottom of the feeding roller 22, the first servo motor 25 is started so that the feeding roller 22 can drive the brush head 26 to rotate. At this time, the molten resin can enter the inner cavity of the brush head 26 through the through groove 23, so that the resin can be applied to the fiber through the brush head 26.

[0048] S3: Start microwave source 2, and adjust the power of heater 4 in conjunction with power amplifier 3 to solidify the fiber filaments.

[0049] S4: When the temperature reaches 70 to 100 degrees Celsius, continue to start the first lead screw 20 to adjust the tension of the fiber filament. At the same time, start the second servo motor 32 to drive the second lead screw 31 to rotate, so that the front drive block 29 can be threadedly connected to the second lead screw 31. This drives the laser length measuring instrument 28 to move, monitor the length of the fiber filament, and limit the length through the laser signal receiver 15. When the laser length measuring instrument 28 moves to the appropriate position, and when the laser signal receiver 15 and the laser length measuring instrument 28 are on the same axis, the tension adjustment component 14 can be stopped, thus completing the adjustment of tension and dimensional accuracy.

[0050] S5: The remaining resin after application will fall into the inner cavity of the recycling tank 21.

6. The method for a microwave curing tunnel furnace for ultra-large diameter carbon fiber composite materials according to claim 1, characterized in that: The procedure includes the following steps: S1: Lift the handle (13) upwards, causing the tightening plate (9) to leave the inner cavity of the first tightening groove (8), and wind the left side of the fiber filament around the outer wall of the winding post (7). After releasing the handle (13), the spring (11) drives the tightening plate (9) to press down through the connecting post (10) to fix the winding post (7). Place the right side of the fiber filament in the inner cavity of the second tightening groove (16), start the electric slide rail (18), and drive the anti-slip pressure plate (17) to press down until the fiber filament is clamped. S2: The melted resin material is injected into the inner cavity of the feeding roller (22) through the feed pipe (24). The first screw (20) is started so that the front of the bottom of the tension adjustment component (14) can be connected to it by the thread. At this time, the fiber can be driven to move to the right side of the inner cavity of the curing equipment body (1) through the tension adjustment component (14). After moving to the bottom of the feeding roller (22), the first servo motor (25) is started so that the feeding roller (22) can drive the brush head (26) to rotate. At this time, the melted resin can enter the inner cavity of the brush head (26) through the through groove (23). In this way, the resin can be applied to the fiber through the brush head (26). S3: Start the microwave source (2) and adjust the power of the heater (4) in conjunction with the power amplifier (3) to solidify the fiber filaments; S4: When the temperature reaches 70 to 100 degrees Celsius, continue to start the first lead screw (20) to adjust the tension of the fiber filament. At the same time, start the second servo motor (32) to drive the second lead screw (31) to rotate, so that the front drive block (29) can be threadedly connected to the second lead screw (31), thereby driving the laser length measuring instrument (28) to move. While monitoring the length of the fiber filament, the laser signal receiver (15) performs length limiting work. When the laser length measuring instrument (28) moves to the appropriate position, and when the laser signal receiver (15) and the laser length measuring instrument (28) are on the same axis, the tension adjustment component (14) can be stopped, thereby completing the adjustment of tension and dimensional accuracy. S5: The remaining resin after application will fall into the inner cavity of the recycling tank (21), and be drawn into the inner cavity of the recycling component (33) through the extraction pipe (36). The electric heating wire (34) is activated to heat it and melt it again. The third servo motor (37) is activated to drive the scraper (38) to rotate and stir it. It can be injected again through the hose (35).
